MATH 342

For each problem, you will have to determine the design. Your design choices are Randomized Block Split Plot, Split Plot, ANCOVA, Crossover, Repeated Measures, Nested Design, Latin Square, Random Effects, Fixed Effects, and Mixed Effects (in that order). So if it is a Nested design with fixed treatments, you will answer Nested Design, not Fixed Effects

Q)

The temperature of a process in a manufacturing industry is critical to quality control. The researchers want to characterize the sources of this variability. They choose 4 plants, 4 operators within each plant, look at 4 shifts for each operator, and then measure temperature for each of three batches per shift used in production.
